Answer:
The width of the new phone will be 4.37 inches
Step-by-step explanation:
Proportions
A direct proportion is a relation between variables where their ratio is a constant value.
The original length of a cell phone was L=1.2 inches and the original width was 4.6 inches.
A new version of the cell phone is to be released with proportional dimensions with respect to the original cell phone.
We are given the length of the new phone L'=1.14 inches. The ratio of the lengths is 1,2/1.14=1.053.
The new width should be W'=4.6/1.053=4.37 inches
The width of the new phone will be 4.37 inches

Complete a paragraph proof for: Given: -4k + 2(5k - 6) = 3k - 36 Prove: k=-8. can someone please help me
The value of k is proved to be -8
How to prove that the value of k is -8?The equation is given as
-4k + 2(5k - 6) = 3k - 36
Open the bracket in the above equation
So, we have
-4k + 10k - 12 = 3k - 36
Collect the like terms in the above equation
So, we have
-4k + 10k - 3k = 12 - 36
Evaluate the like terms in the above equation
So, we have
3k = -24
Divide both sides of the above equation by 3
So, we have
k = -8
Hence, the value of k is proved to be -8

what single decimal multiplier would you use to decrease 1% followed by a 3% decrease?
find the value of -24/35÷-8/15
Answer:
9/7
Step-by-step explanation:
-24/35 ÷ -8/15
=-24/35 × -15/8
=9/7
Answer:
9/7
Step-by-step explanation:
when dividing with a fraction, the -8/15 reciprocates to 15/-8. Then, -8 cancels out -24 remaining with 3 since they are both negative while 15 and 35 have a common of 5 giving them a remainder of 3 and 7 respectively. you then multiply what you have which is 3/7 * 3/1 giving you 9/7.
Given that x is a nonnegative number, a student conjectured that x + 3 < x2.
Which value of x is a counterexample to the student's conjecture?
A: x= -1/3
B: x= -3
C: x= 2
D: 3
Answer:
C (x = 2)
Step-by-step explanation:
Since x is a non-negative number, A and B are eliminated.
This leaves C and D.
C: x = 2,
2 + 3 < 2^2
5 < 4 is false.
So C would be a counterexample.
Hope this helps!
The value of x is a counterexample to the student's conjecture (x = 2). The correct option is C.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that x is a non-negative number, a student conjectured that x + 3 < x².
Since x is a non-negative number, A and B are eliminated.
This leaves C and D at the value of x = 2,
2 + 3 < 2²
5 < 4 is false.
Therefore, the value of x is a counterexample to the student's conjecture (x = 2). The correct option is C.

Step-by-step explanation:
When you have two points you need to use the slope formula:
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_1}[/tex]
x1 and y1 is the first point and x2 and y2 is the second point, remember that the first number is X and the other is Y so...
[tex]m=\frac{5-4}{3-1} \\m=\frac{1}{2}[/tex]

Using proportions, the amount of acres that each children will be is given by:
9 and 4/5 acres.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For this problem 49 acres will be split evenly across 5 children, hence the amount that each will get is:
A = 49/5.
The quotient of 49 and 5 is of 9 with a remainder of 4, hence as a mixed number, the amount is:
9 and 4/5 acres.

the ratio of 82 and 73
Answer: 82:73
Step-by-step explanation:
To find an equal ratio, you can either multiply or divide each term in the ratio by the same number (but not zero). For example, if we divide both terms in the ratio 3:6 by the number three, then we get the equal ratio, 1:2. Do you see that these ratios both represent the same comparison?

The cost to rent a paddle boat at the county park is $8 per hour plus a nonrefundable deposit of $10. The cost can be modeled by the function f(h) = 8h + 10, where
h represents the number of hours the boat is rented. Describe the graph of g(h) as it relates
to f(h) if the nonrefundable deposit increases to $15.
When the non-refundable fee increases to $15, the y-intercept is also increased to 15. The graph are parallel to each other but only touches the y-axis at 10 and 15 respectively
Linear EquationLinear equations are equations of the first order. The linear equations are defined for lines in the coordinate system. When the equation has a homogeneous variable of degree 1 (i.e. only one variable), then it is known as a linear equation in one variable. A linear equation can have more than one variable.
Linear equations are generally represented in the form
y = mx + c
c = y-interceptm = slopeThe y-intercept is the point at which the graph touches the y - axis
In the question, we are given an equation f(h) = 8h + 10
The slope and y - intercept here are 8 and 10 respectively.
However, when the non-refundable deposit is increased to 15, the y - intercept is increase by 5 units to becomes 15.

What is the length of NM?
Answer:
See below :)
Step-by-step explanation:
We know that these traingles are all similar. We can see the angle NMK is 60 degrees so we also know that JNK is 60 degrees. Now we know that all of the triangles are 30-60-90 triangles. JN is 3, so from the "leg opposite to 30 degree theorem", we know that NK is two times JN which is 6. Then from the same theorem, we know that NM is NK divided by the square root of 3
[tex]\frac{6}{\sqrt3}[/tex]
We can't have fractions that have irrational numbers in the denominator of a fraction so we multiply it by root3 over root3
[tex]\frac{6}{\sqrt3}[/tex] * [tex]\frac{\sqrt3}{\sqrt3}[/tex]
This then makes it 6 times root 3 over 3
[tex]\frac{6\sqrt3}{3}[/tex]
We then get [tex]2\sqrt{3}[/tex]
